Resin injection is undertaken using foaming polyurethane resins injected using either hand or mechanical pumps. The technique works on both high and low water flow leaks. It involves drilling holes into the leak, inserting packers and injecting the leak sealing resin through the packers. MaxBuild is a specialist installer of Normet resin injection products.
